Write the corresponding Assembly Code

The following C code shows an implementation of a routine to compute the factorial of its argument, written n!, with a do-while loop. This function only computes the proper value for n > 0.

Assuming that the registers %eax and %edx are used as follows

Write the corresponding assembly-language code, assuming that

Argument: n at %ebp+8

Registers: n in %edx, result in %eax
